Sun on a roof in Richmond.
The PVWatts model puts a generic roof array in Richmond at 1,435 kWh a year for each kW of panels, using typical-year weather from a station 2.2 km away. A modeled estimate for a standard setup, not a measurement of any roof.

How Richmond comparesderived from the figures above
Where Richmond sits.
Richmond ranks 1081st of 1220 Texas places modeled here, at the 11th percentile. Its 1,435 kWh per kW is below the Texas median of 1,515. The strongest months are May, July, August and the weakest are December, February, November; output peaks in May and bottoms out in December. In all, 29.1% of the year arrives in June, July and August, less than the 29.3% of the median place.

Against Houston
The nearest of the six largest modeled places is Houston, 43 km to the northeast, at 1,422 kWh per kW. Richmond models 13 kWh per kW (0.9%) above it. The two figures are within 1 percent, which is about the size of the difference you get from two neighboring weather stations alone, so this page's result is effectively the same as Houston's.
The second-nearest large place is Austin, 208 km northwest, where the same model gives 1,483 kWh per kW, so Richmond runs 48 below that figure. It runs at least 2% lower in February, April, May, June, July, August, September, November, December.

Electricity prices nearby
EIA lists CenterPoint Energy Houston Electric in this county. Where Richmond is on CenterPoint Energy Houston Electric's lines, homes buy energy from a retail electricity provider and the price depends on the plan. Parts of Richmond may instead be served by a co-op or utility listed below, which sets its own rates; check your bill. For scale only, the median 2025 average price across the 60 Texas retail providers on this site is 15.32¢ per kWh, which would put the modeled 1,435 kWh at $220 per kW a year, plain multiplication and not a savings estimate or an offer.
Also listed in the county
- CenterPoint Energy: 5.41¢ per kWh, delivery charges only, before the retail energy price, 2,529,039 residential customers across 12 counties.
These utilities serve other parts of the county, which can include parts of Richmond. They are the largest bundled providers, and the largest delivery-only one, whose EIA service territory lists the county. A county can list several, and which one serves a street depends on the address, so check your bill.

Size the array, see the kWh.
Scale the Richmond model to another array size, take off extra losses for shade or dirt, and price the energy at any rate. It is arithmetic on the PVWatts output above, nothing more: not a quote, not a savings estimate and not advice.
Starting rate: the Texas residential average of 15.4¢ per kWh. At that rate the modeled output is worth $221 per kW a year as plain multiplication.

Getting a measured number
A model cannot see your roof. Installers measure pitch, shade and the electrical panel on site. Quote marketplaces such as EnergySage, SolarReviews and WattBuy collect bids from local installers. Rate & Roof does not rank installers.

Payback, buyback.
The sliders above price the energy at one rate. The payback calculator adds the system cost and your buyback plan type, and shows every assumption. It is an estimate, not advice.
